Researchers at McGill University have developed a new, low-cost method to build DNA nanotubes block by block - a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in applications such ...

Terpenes and their derivatives exert important biological and pharmaceutical functions. Starting out from a few basic building blocks nature elegantly builds up complex structures. Chemically particularly challenging are ...

French artist Paul Gauguin is well known for his colorful paintings of Tahitian life—such as the painting that sold recently for nearly $300 million—but he also was a highly experimental printmaker. Little is known, however, ...

(Phys.org)—A team of researches affiliated with several institutions in Japan has conducted research into the cellular structure of tight junctions in the small intestine, and has made progress in better understanding their ...

Facing a challenge akin to solving a 1,000-piece jigsaw puzzle while blindfolded—and without touching the pieces—many structural biochemists thought it would be impossible to determine the atomic structure of a massive ...

More than 80 percent of microbial infections in the human body are caused by a build-up of bacteria, according to the National Institutes of Health. Bacteria cells gain a foothold in the body by accumulating and forming into ...

Proteins are the building blocks of all living things, and they exist in virtually unlimited varieties, most of whose highly complex structures have not yet been determined. Those structures could be key to developing new ...

A joint research group successfully developed a material that expresses a unique mechanical property by arranging oxide nanosheets, that electrostatically repel each other, in the direction perpendicular to a magnetic field, ...

Structure

Structure is a fundamental and sometimes intangible notion covering the recognition, observation, nature, and stability of patterns and relationships of entities. From a child's verbal description of a snowflake, to the detailed scientific analysis of the properties of magnetic fields, the concept of structure is an essential foundation of nearly every mode of inquiry and discovery in science, philosophy, and art.

A structure defines what a system is made of. It is a configuration of items. It is a collection of inter-related components or services. The structure may be a hierarchy (a cascade of one-to-many relationships) or a network featuring many-to-many relationships.
